What we Learnt
 Average of 12.4 kw/day of air con usage in homes. (Panasonic CS-S12NKZW Econavi).
 48 liters of grey water being wasted per day per apartment.. (based on the 2 liter flow rate
provided by PUB.)
 In all applications, there will always be a percentage of energy that is always wasted.
 We decided against focusing our project on changing people’s habits but rather adapting
technologies to reduce wastage from everyday habits or lifestyle.

Proposed Solutions
Microturbines
Sledges to be inserted on HDB
walls to collect rainwater which will
drip into the pipe.
Rainwater falls
through pipes,
turning
microturbines in
the process
As it flows downwards due to
gravity, it will turn turbines to
generate electricity to power lights.
After which this water would flow
into a storage container to be used
for ie drip water irrigation.
Biofuel Digester
Students will
throw their
waste after
eating
Organic
methane
• Implemented in the
kitchen
• Will be roughly the size of
a dustbin. When
connected to the gas
stove, it could be used for
cooking purposes,
eliminating the need for
electricity.

Feedback
Having people use them and
getting back feedback for the
design of our products
Prototyping Creating site

Brainstorming to come
up with viable ideas
Experimentation
Interacting with our
prototypes and observations.
Improvisation
Looking at the flaws of our
design and coming up with
ways to improve them
Checklist
to combine everything for a HDB flat
What are some of the parts in each idea that is compatible with one
another?
How would electricity be harnessed from the biogas generators?
What are the materials we can use to make it as cost efficient as possible?
What are the different ways in which we can channel the generated
energy?
